Wild plant species related to crop plants form an important source of useful traits for fruit quality improvement and biotic abiotic stress tolerance. Wide hybridization involving wild relatives taxa has gained momentum in the recent programs. It breaks barrier gene transfer makes it possible genome one another, which results changes genotypes phenotypes progenies. The incompatibilities or barr...

Polyploidy has played an important role in higher plant evolution and applied plant breeding. Polyploids are commonly categorized as allopolyploids resulting from the increase of chromosome number through hybridization and subsequent chromosome doubling or autopolyploids due to chromosome doubling of the same genome. Allopolyploids undergo bivalent pairing at meiosis because only homologous chr...

Abstract Genetic circuits that control specific cellular functions are never fully insulated against influences of other parts the cell. For example, they subject to periodic modulation by cell cycle through volume growth and gene doubling. To investigate possible effects on oscillatory dynamics, we modelled a simple synthetic genetic oscillator, repressilator, studied hallmarks resulting nonli...

Solanum melongena is susceptible to diverse diseases and parasites, in particular the wilts (bacterial, Fusarium Verticillium), nematodes, some insects. torvum robust Verticillium bacterial root-knot nematode. It was reported that interspecific hybrid plants originated out of hybridization these species were sterile. In our previous studies have been carried overcome this barrier, only from Fas...

We develop criteria to detect neighborhood selection effects on gene loss following whole genome duplication, and apply them to the recently sequenced poplar (Populus trichocarpa) genome. We improve on guided genome halving algorithms so that several thousand gene sets, each containing two paralogs in the descendant T of the doubling event and their single ortholog from an undoubled reference g...

Agmatoploidy is a type of chromosome rearrangement that involves the fragmentation of an entire chromosome complement, generating a diploid with double its original chromosome number. Agmatoploidy and other related karyotype changes, such as symploidy (the opposite change, promoted by chromosome fusion), partial agmatoploidy, polyagmatoploidy, etc., are restricted to species with holokinetic ch...
